Post Utme Wellspring University 2024 Chemistry Objective / Multiple Choice
Question 6 POST_UTME_WELLSPRING_UNIVERSITY • 2024 • CHEMISTRY • objective

Determine the rate cons\tant (k) for the reaction: 2NO(g) + O2(g) → 2NO2(g), given that the initial concentrations of NO and O2 are 0.1 M and 0.05 M, respectively, and the rate of reaction is 0.02 M/s after 10 minutes.

Answer Options

A. \( k = \frac{2.303}{t} \log left\( \frac{[NO]_0 [O_2]_0}{[NO_2]_t} \right \ \) )
B. \( k = \frac{2.303}{t} \log left\( \frac{[NO_2]_t}{[NO]_0 [O_2]_0} \right \ \) )
Correct Answer C. \( k = \frac{2.303}{t} \log left\( \frac{[NO]_0 [O_2]_0}{[NO_2]_t} \right \ \) )
D. \( k = \frac{2.303}{t} \log left\( \frac{[NO_2]_t}{[NO]_0 [O_2]_0} \right \ \) )
Correct Answer
C
Correct Option:
\( k = \frac{2.303}{t} \log left\( \frac{[NO]_0 [O_2]_0}{[NO_2]_t} \right \ \) )
